What Is an AI Detector?

An AI detector, also called an AI checker, analyzes text to estimate whether it was written by AI. Paste your text into OpenL to get an AI score, compare AI-generated and human-written percentages, and review highlighted sentences that may look AI-written. It works best for English text and is useful for students, teachers, editors, marketers, and content teams who want a quick authenticity check before publishing or submitting content.
